Zumwalt class destroyer

-

New age of warfare has transform the way Navy design their battleship. Hence in November 2001, the US Department of Defense announced that the DD 21 programme for the future surface combatant had been revised and would now be known as DD(X). The programme focus would now be on a family of advanced technology surface combatants, rather than a single ship class.

In November 2005, DD(X) was approved for system development and demonstration (SDD). In April 2006, the USN announced that the first ship of the class will be designated DDG 1000 Zumwalt. The second ship will be Michael Monsoor (DDG 1001).


The DDG-1000 is planned to feature the following: a low radar profile; an integrated power system, which can send electricity to the electric drive motors or weapons, which may someday include railguns or free-electron lasers total ship computing environment infrastructure, serving as the ship's primary LAN and as the hardware-independent platform for all of the ship's software ensembles; automated fire-fighting systems and automated piping rupture isolation.

DDG 1000 will have a 'tumblehome' hull form, i.e. a design in which hull slopes inward from above the waterline. This will significantly reduce the radar cross section since such a slope returns a much less defined radar image rather than a more hard-angled hull form.

Mr.Lee failed to perform a couple of important lesson which lead to his demise which is when one park he’s or her’s vehicle especially a 3 tonne truck to unload any sort of goods it pays to have a common sense to turn off the engine. No matter how long the stop takes or how long one driving experience has in his/her entire life. And secondly the parking brakes are installed for a reason. It pays to use it when parking. Where Mr.Lee fail in common sense makes up in creativity or in this case uniqueness on how to get a first class ticket boarding flight to St. Peter’ gate. As Mr.Lee got down from his 3 tonne truck to unload the bricks he left the engine running while uploading the brick from the back of the truck. The 3 tonne truck moved backwar...
